All songs written and composed by Twenty One Pilots. Tyler Joseph - lead vocals, keytar, piano, synthesizer Nick Thomas - bass guitar, keyboard (former member) Chris Salih - drums (former member) This was the only release confirmed that Nick Thomas and Chris Sailh worked on besides a few singles before their departure from the band. After the debut album, the band's general sound and genre changed profoundly, notably from a much darker sound to a lighter sound. The spiritual overtones and Christian metaphors that have been found throughout the band's music career are seen more obvious on the debut album than on any of their following releases. (wiki)
